BOILER.

Application led October 25, 1919. Serial No. 333,194.

This `.invention relates to steam boilers,

and particularly to boilers of the tube type, wherein water is circulated through heated tubes.

The main object of this invention is the provision of means to increase circulation through the boiler tubes', thereby preventing the water from backing up at the ends of the tubes. r

A further object of the invention is to construct a boiler head wherein the tubes are held in spaced relation by suitable plates which form partitions, for partitioning the heads into compartments. f

Referring to the drawing Figure 1 illustrates a sectional view through a tube boiler. f

Figure 2 is a modified form of header.

Figure 3 is a vertical sectionalview taken on line 3-3 of Figure 2.' l

p view thereof.

Figure 5 illustrates a'sectional lviewof a modified form of header. Y

Figure 6 illustrates a horizontal sectional Referring-to the drawings in detail, reference character 5 indicates a header, which has communioationat its upper end with the 4boiler 6 through nipple 7, and with the opin alignment with the openings 10 of the Vrear wall 9, for purposes to be hereinafter more fully described.

To facilitate the circulation and heating of the water within the water tubes 11, I have provided a horizontal partition 15 in each of the tubes, one end of the partitions being connected to the respective threaded plugs 16., which are positioned in the openings 10 of the header. These partitions 15 extend through the water tubes 11 and closely engage the inner wall 17 thereof, the in. rner ends of said partitions terminating short of the ends of the water tubes in which the saine are supported, to provide a space between the yends of the partitions and their tubes, thereby allowing free passage of fluid through `the compartments formed in the tubes by the partitions.

In the modified form of the invention, as shown by Figure 4 of the drawings, the water tubes 11 are arranged in groups, each group having an independent header 12 t0 which'the water tubes 11 are connected. These headers `12', as shown, have communication with the boiler proper 122, through vertical pipes 132, and said pipes having one of their ends connected to the heads through the openings 142 formed in they upper walls of the heads 12.

As indicated by the drawings, each of the tubes 11,.is provided with a central partitiony dividing the same into compartments 13 and 14', whereby circulation through the tubes 11 is maintained, at all times.

With reference to Figure 2, the same illustrates a modified form of a header, which as shown has curved walls 20, an intake opening 21, at the bottom thereof and eX- haust opening 22 at the top, the curved side walls of the header forming irregular passage ways for water circulating around the ends of the water tubes 23, which as shown are disposed in staggered relation with each other. A drain opening 28 is provided `at the base of the header to permit the water within the boiler and tubes to be drained off and replenished.

Metallic partitions 24 and 30 divide the header into vertical compartments 25 and 26,

which compartments communicate through the water tubes 23, the partitions 24 and 30 contact-ing with the ends ofthe tubes.

In Figure 1 of the drawings I have shown a burner 27 disposed.` directly under the water tubes 11. This burner, however, may of course be supplemented by the ordinary fire box, as illustrated by Figure 4.

Having now described my invention, what I claim is r- Y n In a boiler construction, a body portion, a

header at one end of the body portion, tubes extending into the body portion and communicating withthe header, said tubes being disposed in staggered relation withrespecty to each other, removable partitioning members, alternate vertical and ohliquely disposed partitioning Walls in said header contacting with the ends of .adjacent tubes and with opposite edges of the respective removable partitioning members to form two longitudinal passages through said header,

there being au inlet to one of said passages through one end of the header, and an outlet for the other passage at the opposite end 10 of said header.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.

FELIX LOUIS DECARIE.
